We’re building a robotics system that recovers reusable electronic components from retired hardware. To run experiments we’re looking to buy electronics that are *retired or obsolete but still contain valuable components*.
We’re especially interested in hardware that *is no longer useful as a system but still has valuable chips or components on the boards*.
Typical pricing depends on the hardware, but we often pay *$20–$200+ per unit* for things like servers, networking gear, or laptops depending on what’s inside. Happy to buy bulk lots.
Based in the Bay Area; we can arrange pickup locally or pallet shipping within the US.

Even rough descriptions like “a pallet of old switches” are helpful.
There are e-waste companies with inert hot-air centrifuges. Essentially, they extract the RoHS solder, clean it, and resell re-certified product back to manufacturers.
The chips simply drop off into a bin, and no ethical company will sell customers used silicon. There were a few folks that ended up getting a few years in prison for that con (small China groups would sand and laser mark old chips with modern lot codes), and hence why many US recycling plants shred the chips for recovery of precious metals.
It is a serious safety problem, and having personally been stung by locally sold counterfeit/used stuff with BS compliance documentation... it sometimes means months of lost project time figuring out what happened. Always direct sample from the manufacturers whenever possible. =3
I can't see a problem, as long as the chips are not fraudulently resold. Beyond not using a resource in the first place, reuse is the gold standard in sustainability.
As an engineer, I wouldn't use second hand components for prototyping. When prototyping you need to eliminate as much uncertainty as possible. I'd consider using second hand components in production, provided there is a cost advantage, supply is reliable and my production line includes a test that would pick up faulty components. Even then, I'd be monitoring failure rates and reverting to new components if elevated failure rates caused costs. There's an argument that (well handled) second hand components might even have a lower failure rate than new as they have been burned in.
I'm guessing this company is targeting specialsied repair rather than production. Sometimes complex parts are no longer manufactured and the only option is second hand (often at a premium price).
>I can't see a problem, as long as the chips are not fraudulently resold.
In general, most components are only rated for 2 to 4 re-flow heating cycles before internal damage occurs. On some components the initial re-flow cycle brings the component into the rated tolerance, and for others the PCB forms a bimorph cantilever that physically fatigues the chip contacts/leads.
Production yields are only part of the Infant Mortality Phase of the bathtub curve.
Some components do get more stable with age if and only if left alone, but you can count those on one hand if you still have all your fingers. That is also a 3 hour pedantic conversation no one wants to have.
the way we see it is that with robotics and coding agents we can offer much comprehensive and traceable tests. anyone can send any hardware they have, we help understand what is reusable, how to verify it and ship the parts back.
curious—what specific failure modes or uncertainties would you want eliminated before you'd consider using recovered parts, even just in production?

Since when? My first EE job was in 1988 and back then "pulls" -- components pulled from circuit boards were an easy way to get cheap parts. We'd get mailers every week from various companies listing what they had available. The electronics recycling industry was/is huge.
Good point that I hadn't thought of. I figured that the reason I hadn't seen any pulls in recent memory was because I didn't work in the segment of industry that was so cost-sensitive any more.
While we only used DIPs at that time, most of the pulls that I remember weren't removed from sockets: they had clearly been desoldered.
exactly!! we aim to have comprehensive and transparent protocols of testing after the extraction which is exactly what is hard without general purpose robotics. if you have any pointers on how to make that happed or any pain points from your experience please send me a note to sava@dayworkx.com !
I am not the poster...but I can say for things like the A4982 stepper drivers it would take me about 1-2min/chip to do it by hand with hot air with a preheater. [1]
In one particular case where we had a BOM mixup on a batch of 500 boards @5 chips per board this would have saved me a ton of time. I did 2500 chip swaps by hand...
If you need any help with the project let me know. This is something I would love to help develop hardware for.
that's true, but we've only seen either highly specialized hardware that forces you to lock in or a methods (tumbling / rotary shredding) that destroy the components. we want to leverage general purpose policies more to make the cost of setting up "hardware reuse" nodes less and thus the whole supply chain more distributed and robust.
So I send in massive 60 drive jbod pcbs and you pay me more than 55c/lb? That's current clean pcb rate at any recycler. Boards are ~8lbs ea. Usually just tossing them unstripped to a muncher that pays 35c/lb for the whole 55lb jbod works out way better for time labor.
I guess the prime target for this would be USB-C controllers? Ubiquitous and expensive enough to justify building a machine and yet versatile enough that you could find a second hand market for them.
Looks like a hot-air rework setup. I've swapped chips by hand that way, once the solder is molten they'll fall right off the board. The hard part is lifting them away without accidentally dislodging anything else.
exactly, + we preheat the board before to let the trapped air out. would love to hear more about your experience doing this by hand and where you see automations for this applicable
thank you for all the support so far! We've got a lot of inbound and started processing it. there are a lot of interesting questions on this thread and i'll address them soon.
Examples:
* servers, networking gear, routers, switches * laptops / workstations * telecom / industrial / embedded boards * lab equipment electronics * obsolete or end-of-life hardware with populated PCBs
